What to do when you experience poor quality of power supply. Problems related to quality of power supply can be experienced as voltage fluctuations, power surges and spikes. They commonly cause lights to flicker, glow brighter or dimmer and can even cause incandescent bulbs to blow prematurely. Poor power supply can also cause electronic equipment to fail (especially computers) and may cause interference of radio or television reception.
Static interference and harmonic distortion are electrical disturbances caused, for example, by air conditioners, vacuum cleaners, hair dryers and cordless phones. A leading cause of electrical trouble for home computers, they can also create serious problems for stereo, radio, security and phone systems.
